Created by deep erosion of limestone rock, Johnston Canyon flows unstopped from the high mountain regions of Banff National Park to the Bow River below.

Along Johnston Creek are many beautiful waterfalls and blue-green pools but this only represents the calm conditions of modern day. This canyon's history is long and violent where the water once flowed so powerful that giant underground caverns were formed in the wake of powerful, flows.

This image depicts one of the mighty remnants of Johnston Creek, an enormous limestone extrusion, captured from deep within one of the very caverns this tributary created long ago and it's scale conveyed by the small human figure that looks upon it in amazement.
